What is Lymphoedema?
Causes, stages
and conservative

Lymphoedema is a chronic disease of the lymphatic system affecting 250 million people worldwide. Understanding the condition is the first step towards effective management.

THE CONDITION

What happens in the body?

The lymphatic system is a network of vessels and lymph nodes that collects lymphatic fluid from the tissues and returns it to the bloodstream.
When this network is damaged or forms incompletely, fluid accumulates in the tissues, causing chronic swelling.

Swelling mainly affects the arms or legs, but can also affect the neck, chest, face or genitals. Without proper management, the condition progresses over time.

Primary Lymphoedema

Arises from genetic or congenital causes — present at birth or manifesting during puberty or adulthood. It is rarer, representing about 10% of cases, and is often diagnosed late.

Secondary Lymphoedema

The most common form, caused by external damage to the lymphatic vessels. Main causes: oncological surgery (e.g. mastectomy with lymph node removal), radiotherapy, parasitic infections (filariasis), trauma or severe obesity.

PROGRESSION

THE 4 STAGES OF LYMPHOEDEMA

Lymphoedema progresses through four stages. Early diagnosis and consistent conservative therapy can slow or stabilise progression.

0 Stage

Latent Lymphedema

A subclinical phase in which the lymphatic system is damaged but does not yet show visible swelling. There may be a sensation of heaviness.

1 Stage

Reversible

The edema is soft, increases during the day, and disappears or is significantly reduced with rest or by elevating the limb. Pressure causes a “fovea” to form (fovea sign).

2 Stage

Irreversible

The edema persists even at rest, and the skin begins to show signs of fibrosis (hardening) due to chronic inflammation. The fovea may no longer be present.

4 Stage

Elephantiasis

 Advanced and severe stage. The swelling is massive and hard, with marked fibrosis, skin changes (papillomatosis), and increased limb volume.

What the ‘Fovea’
Sign means

The pitting test is a clinical procedure used to diagnose the presence of edema (fluid accumulation). It involves applying pressure with a finger to the skin for a few seconds: if, after removing the finger, a dimple or indentation remains visible for up to 20 or even 30 seconds, the test is considered positive for lymphedema and is therefore used in diagnosis.
